RETAINER FOR COMPOSITION ROOFING.

Application filed February 24, 1926. Serial No. 90,304.

place thereon, to preclude thefiappingor curling of the strip shingles or roll roofing which constitutes the roof covering.

Devices for this general use have been heretofore suggested but, for various fully sufiilcient reasons have not been found practica The object of this invention is to provide a thoroughly practical retainer and one which will be acceptable to the trade.

With these considerations in mind, the present invention consists of a-sheet metal stamping. In its preferred form, it con; prises a body portion or plate provided with fingers returned upon themselves to form hook-shaped portions or keepers, and from the material which forms the body portion,

' a tapering or pointed spike portion or tongue is stamped out and bent into, angular relation to the body portion, the said spike ortion or tongue being disposed in a plane between the said keepers so as to better hold the shingle in place on the roof.

It is of importance that the spike portion extend from the body portion, interiorly of the edge of such portion, so that there is an appreciable extension of the body portion beyond the base of the spike portion iii all directions Thus the body portion forms, in effect, the head of the spike portion and the said extension not only facili tates driving of the spike portion, but also overcomes the tendenc of the device to bend at the junction 0 the body and spike portions, as would be the case if the spike portion were pp it ip ned at the very edge 01 the body portion.

It is of further importance that during the manufacture of the device, the spike portion is manipulated in a forming die to channel or crimp this portion longitudinally so that it is transversely substantia y V sha d or U shaped. Thisoperation mate rial y strengthens the spike portion against bending during the driving operation.

All of these features unite to provide a unitary structure which is easily attached .and' thorou hly efiicient in the performance of-its inten ed functions.

Features of the invention, other than those specified, will-be apparent from the hereinafter detailed description and claims, when read in conjunction with-the accompanying drawings. p

The accompanying drawings illustrate different practical embodiments of the invention, but the constructions therein shown are to be understood as illustrative, only, and not as defining the limits of the invention.

Figures 1 to 3, inclusive, are perspective views showing .diiferent forms of the invention; and,

Figure 4 is a side elevation of a retainer but having a spike portion positioned at an acute angle with respect to the body portion of the retainer.

Referring first to Figures 1 and 4, 1 is a sheet metal plate or body portion provided at one end at each edge with a finger 2*, re-

turned upon itself to form a keeper having a re-entrant recess 3 into which the edge of a shingle or roll roofing is adapted to be received. Portions of the body of the plate are stamped out, as shown at 4, to provide a tapering or pointed finger or spike portion 5%, which may extend in right an relation to the plate 1, as shown in Figure 1, or in acute angular relation thereto, as shown in Figure 4.

The entire article is integrally formed from sheet metal, manipulated in suitable cutting and forming dies, and, during the forming operation, the spike portions 5 are longitudinally channe ed. In this operation, the cross section is preferably madeof either V or U shape, so as to render the spike portions suiiiciently rigid to permit of their being driven into a roof without bending.

Moreover, I have found inpractice that, by thus forming the spike portions, they will drive easier and will held tighter, than if they are transversely flat. 7

In Figure 1 a single spike portion 5 is cut from the plate 1, and the cut out 4* is extended to the edge of the plate, so that when the end of the ate is returned upon itself to form the re-entrant recess there will be two spaced fingers 2 and two alined recesses 3 In' Figure 2, the plate 1 is shown as stamped out at 4' to form the s ike portions 5 and spaced fingers 2 are ormed along one longitudinal edge of said plate.

In Figure 3, the plate 1 is in the form of a strip, successive longitudinal parts lar of which are out of alinement. The spike portions 5 are stamped out ofthe body of the plate in the same manner. as hereinbefore explained, and the ends of the plate are returned upon themselves to constitute the fingers 2 forming the re-entrant re cesses 3.

The foregoing embodiments of the invention are illustrative of many numerous forms of which the invention is susceptible. In every case, however, the underlying construction is the same; that is to say, the

- spike portions 5, 5 and 5 are stamped out of roofing. In this manner, the retainer is rigidly secured tothe roof in position to cooperate with roofing of the next course. The device is thus easily and expeditiously fixed in position.

- The invention is simple in construction and can be made by automatic machinery in an economical, expeditious and eflicient manner. In practice, the plate or body portion of the retainer may be of any suitable shape and the spike portion can be positioned at an appropriate angle, without departing from the spirit and scope of the invention, which is commensurate with'the appended claims.

The invention has, for the purpose 0% illustration, been described as a shingle readapted for general application in the various arts.

Having thus fully described the invention what I claim as new and desire to secure by Letters Patent is:

1. A device of the character described, comprising a sheet metal body portion, spaced-apart keepers on the body portion and forming re-entrant recesses, and a spike portion stamped from the body portion and cut into angular relation thereto, said spike portion extending from the body portion between and out of longitudinal alignment with said keepers.

2. A device of the character described comprising a sheet metal body. portion,

hook-shaped keepers integral with the body portion and forming re-entrant recesses adapted to receive a portion of a shingle, and'spike ortions stamped from within the confines of the body portion and bent into angular relation to said body portion, said spike portions being between andout of longitudinal alignment "with the keepers.

3. A device of the character described, comprising a sheet metal body portion, hooked-shaped keepers integral with the body portion and forming re-entrant recesses adapted to receive'a portion of a shingle. said keepers-being spaced apart, and spike portions stamped from within the confines of theibody portion and between and out of longitudinal alignment with the said keepers, the said spike portions being of angular cross section.

tainer, but it will be understood that it is said In testimonyiwhereof I have signed. the

foregoing specification.
